I disagree with both scenario.
I am interested in hearing when you think it's the time to move WW up top and Rashford onto left wing because IMO it's obvious from the first minute that WW shouldn't be on the pitch in this game.
Without Rahsford's pace, Liverpool would be even more comfortable at the back. Despite VVD's decline, he won't have issue with someone like WW who is slow, not really good in the air. Without a quality CF to play off, Rashford may beat TAA, but he would run into Konate and stuck in a tactical stalemate again. Playing as CF, Rashford can target VVD side of Liverpool defense, which he did with some positive play.
Klopp had ETH pressing plan beaten. Our midfield was outfought, outnumbered. Our attack lacks creativity and support because Bruno was shifted to unfamiliar position, and Weghorst lag behind the tempo of our faster players in counter attack. We gambled on the fast transition, but unfortunate WW is even slower than Liverpool aging slow midfield. In the opposite end, when Liverpool went direct, quick transition, WW was not there to support our other midfielders. We left too much space in the midfield, that despite the bad rep of recent time, Liverpool midfielders got a good comfortable game to catch a breather and did their job.
